-git-pull - Pull and merge from another repository.
+git-pull - Pull and merge from another repository
SYNOPSIS
DESCRIPTION
-----------
-Runs 'git-fetch' with the given parameters.
+Runs `git-fetch` with the given parameters, and calls `git-merge`
+to merge the retrieved head(s) into the current branch.
-When only one ref is downloaded, runs 'git resolve' to merge it
-into the local HEAD. Otherwise uses 'git octopus' to merge them
-into the local HEAD.
-
-Note that you can use '.' (current directory) as the
+Note that you can use `.` (current directory) as the
<repository> to pull from the local repository -- this is useful
when merging local branches into the current branch.

--a, \--append::
- Append ref names and object names of fetched refs to the
- existing contents of $GIT_DIR/FETCH_HEAD. Without this
- option old data in $GIT_DIR/FETCH_HEAD will be overwritten.

-MERGE STRATEGIES
-----------------
-
-resolve::
- This can only resolve two heads (i.e. the current branch
- and another branch you pulled from) using 3-way merge
- algorithm. It tries to carefully detect criss-cross
- merge ambiguities and is considered generally safe and
- fast. This is the default merge strategy when pulling
- one branch.
-
-recursive::
- This can only resolve two heads using 3-way merge
- algorithm. When there are more than one common
- ancestors that can be used for 3-way merge, it creates a
- merged tree of the common ancestores and uses that as
- the reference tree for the 3-way merge. This has been
- reported to result in fewer merge conflicts without
- causing mis-merges by tests done on actual merge commits
- taken from Linux 2.6 kernel development history.
- Additionally this can detect and handle merges involving
- renames.
-
-octopus::
- This resolves more than two-head case, but refuses to do
- complex merge that needs manual resolution. It is
- primarily meant to be used for bundling topic branch
- heads together. This is the default merge strategy when
- pulling more than one branch.
-
-ours::
- This resolves any number of heads, but the result of the
- merge is always the current branch head. It is meant to
- be used to supersede old development history of side
- branches.

EXAMPLES
--------
changes into a merge commit. Small fixups like bumping
release/version name would be acceptable.
+Command line pull of multiple branches from one repository::
++
+------------------------------------------------
+$ cat .git/remotes/origin
+URL: git://git.kernel.org/pub/scm/git/git.git
+Pull: master:origin
+
+$ git checkout master
+$ git fetch origin master:origin +pu:pu maint:maint
+$ git pull . origin
+------------------------------------------------
++
+Here, a typical `.git/remotes/origin` file from a
+`git-clone` operation is used in combination with
+command line options to `git-fetch` to first update
+multiple branches of the local repository and then
+to merge the remote `origin` branch into the local
+`master` branch. The local `pu` branch is updated
+even if it does not result in a fast forward update.
+Here, the pull can obtain its objects from the local
+repository using `.`, as the previous `git-fetch` is
+known to have already obtained and made available
+all the necessary objects.
+
+
+Pull of multiple branches from one repository using `.git/remotes` file::
++
+------------------------------------------------
+$ cat .git/remotes/origin
+URL: git://git.kernel.org/pub/scm/git/git.git
+Pull: master:origin
+Pull: +pu:pu
+Pull: maint:maint
+
+$ git checkout master
+$ git pull origin
+------------------------------------------------
++
+Here, a typical `.git/remotes/origin` file from a
+`git-clone` operation has been hand-modified to include
+the branch-mapping of additional remote and local
+heads directly. A single `git-pull` operation while
+in the `master` branch will fetch multiple heads and
+merge the remote `origin` head into the current,
+local `master` branch.
+
+
+If you tried a pull which resulted in a complex conflicts and
+would want to start over, you can recover with
+gitlink:git-reset[1].
